Application filed August 12,1905. Serial No. 273,993.

To all whom/ it may concern:

Be it known that I, J OSIAH J. DEAL, a citizen of the United States,residing at Canton, Stark county, Ohio, have invented certain new anduseful Improvements in Combination-Locks and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the figures of reference marked thereon, in which-Figure 1 is a perspective view showing a portion of the door and thelock connected thereto for use. Fig. 2 is a view showing the lock-casingand all the different parts properly assembled, illustrating atransverse section of the inner knob-spindle. Fig. 3 is a similar view,except the resetting-disk is removed. Fig.4 is a view showing the firstcombination-disk removed and illustrating the position of one of thenotched or counting disks. Fig. 5 is a view showing the first notched orcounting disk removed and illustrating the partition-plate. Fig. 6 is avertical section of the lock, showing the same properly connected to adoor. Fig. 7 is a detached view of one of the counting-disk-operatingbars and springs. Fig. 8 is a detached view of the friction-spring. Fig.9 is a detached view of the setting disk and pin.

The present invention has relation to combination-locks; and it consistsin the diiierent parts and combination of parts hereinafter described,and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the lock-case,which issecured to the door 2, as hereinafter described. To an inner knobspindle3 is attached the knob 4 in the usual manner, and to the outerknob-spindle 5 is attached the outer knob 6, which knob may be of anydesired construction. The inner knob-spindle is not locked againstoperative rotation and is entirely disconnected from the outer spindle5. To the outer spindle 5 is attached the notched head 7 by means ofscrew-threads formed upon said outer spindle, and the inner spindle 3 isalso attached to said head by means of screw-threads, but is so attachedthat it is free to rotate independent of the head in one direction, andwhen so rotated by means of the inner knob 4 it actuates the bolt 8 inthe ordinary manner, which devices within themselves form no particularpart of the present invention, and hence no description or illustrationis necessary. Directly below the inner end of the outer knob-spindle 5is located the hollow bearing 9, which is formed integral with thelock-case 1 and in which hollow bearing is located the spindle 10, whichs indle is free to be rotated by means of the nob 11. Upon the hollowbearing 9 are loosely mount ed the notched or counting disks 12, 13, and14; but it will be understood that these parts may be duplicated, ifdesired, without departing from the nature of my invention. Between thenotched or counting disks 12, 13, and 14 are located the lock-disks 15,16, and 17, which lock-disks are provided with the square-shoulderednotches 18. Directly above the spindle 10 is located the gravitybar 19,which gravity-bar is provided with the T-head 20, the lower portion ofthe T- head being for the purpose of entering the notches 18 when saidnotches are brought into alinement, as hereinafter described.

The notched head 7 is designed to rotate with the outer knob-spindle 5but it will be understood that said outer knob-s indle cannot be rotatedwhen the T-hea 20 is engaged with the notch 21 formed in the lowerportion of the head 7 but when said head is disengaged from the notch 21the outer knob, together with its spindle, is free to rotate,

which rotation operates the catch bar or bolt 8 in the usual manner. TheT-head 20 is held in elevation at all times, exce t when the notches 18are brought into alinement and directly under the T-head 20, at whichtime said T-head is free to drop and release the head 7. The lock-disks15, 16, and 17 are each provided with a series of apertures 22, whichapertures are for the purpose of re ceiving the connecting-pins 23,which connecting-pins are secured to the notched or counting disks 12,13, and 14, and when the pins 23 are so connected the lock-disks andcounting-disks move togetherthat is to say, one counting-disk and onelock-disk move in unison. It will be understood that by changing thepins 28 into different apertures in the diiferent lock-disks a differentcombination is producedas, for instance, the first or inner lock-diskmay be connected to the a erture 3, the next one aperture 4, an" thethird one aperture 5, which would make the combination 3 4 5.

It is well understood that all of the count ing-disks should be broughtinto such a position that a given combination will open the lock, and inorder to provide for this each counting-disk is provided with a tang 24,and upon the extreme inner end of the spindle 10 is secured the disk orplate 25, which plate is provided' with the pin 26, which pin is solocated that it will come in contact with the tangs 24, and as thespindle 10 is rotated all of the counting-disks, together with thelocking disks, will be brought to a predetermined position by reason ofthe tangs 24 coming in contact with the T-head 20. The movement of thespindle 10, which brings the tangs 24 against the T-head 20, places thelock in position to commence counting the predetermined combination toopen the lock. For the purpose of elevating the T-head after it hasdropped to release the head 7 the disk 25 is provided with the notch 27,which notch is provided with the inclined edge 28 which in? clined edgeermits the T-head to ride upon said incline edge 28 and elevate saidT-head; but by reason of the notches 18 in the lockdisks being formedwith square shoulders or edges said disks will be held against rotationin either direction. For the purpose of operating the variouscounting-disks the counting-bars 29 are provided, which countingbars areeach provided with the outward-extending knobs or lugs 30, and to saidbars are 1 attached the spring-tangs 31, which springtangs engage theteeth 32, formed upon the counting-disks. It will be understood thatwhen any given bar 29 is moved upward it will impart a rotary movementto the corresponding counting-disk by reason of the spring-tang 31. Forthe purpose of providing a means for limiting the upward movement of thecounting-bars 29 the case 1 is provided with the slots 33, which slotsare so formed that they limit the upward movement of the knobs 30. Forthe purpose of insuring the downward movement of the counting-bars theirbottom or lower ends are provided with the notches 34, and into whichnotches are seated the springs 35, as illustrated in the drawings. Forthe urpose of giving the proper tension to the loc -disks, together withthe counting-disks, the spring 36 is provided, which spring is locatedsubstantially as shown in Fig. 2 and of the form shown in Fig. 8 and isdesigned to press against the peripheries of the lock-disks 15, 16, and17. If desired, the spring 36 may be divided at its lower end and onedivision of the spring arranged to come in contact with one lock-disk.For the purpose of holding the counting-bars in proper position at theirtop or upper ends a clip 37 is provided, which clip is connected to thecasing 1 by the flange 38, and of course the spring 36 is located overthe clip and at one side of the connectingfiange 38. It will beunderstood that the various lock-disks and counting-disks should notmove except when necessary, and in order that there may be no accidentalmovement of the various disks the division-plates 39 are provided, whichare held against rotation by means of their notched ends and the pin 40.For the purpose of causing the disk 25 to rotate with the spindle 10 andalso for the purpose of economizing with reference to room said disk isprovided with the slot 41, which slot receives the pin 42. For thepurpose of holding all of the various disks in proper position upon thespindle the key 43 is provided and said key located through the spindle10. For the purpose of stopping the head 7 at the proper point withreference to the T-head 20 the stop-pin 44 is provided, which stop-pinis secured to the casing 1 in any convenient manner, andfor the purposeof causing the head 7 to be forced against the stop-pin 44 the spring 45is provided and located substantially as shown in the drawings, and, asshown, it will be seen that said spring will press the head 7 againstthe stoppin 44 when said head is free to move.

It will be understood the means for actuating the lock-bolt 8 arepractically the same as the means in common use and that no change ofsaid parts is necessary, thereby enabling my improved lock to be adaptedto the common key-locks now in use.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
